Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TFM-145-32-S-D are identified based on electrical and mechanical compatibility within the Tiger Eye™ TFM series. The following parameters remain constant across all substitute relationships:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 90
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary variable parameter is Insulation Height, which differs among substitute parts. The TFM-145-12-S-D-LC and TFM-145-22-S-D-LC both include Board Lock features not present in the main part.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection between TFM-145-32-S-D and its substitutes depends on mechanical clearance requirements determined by Insulation Height specifications:

• TFM-145-32-S-D: 0.435" (11.05mm) insulation height for applications requiring maximum standoff distance
• TFM-145-12-S-D-LC: 0.290" (7.37mm) insulation height with Board Lock feature for compact designs
• TFM-145-22-S-D-LC: 0.360" (9.14mm) insulation height with Board Lock feature for intermediate spacing requirements

All parts share identical electrical ratings, contact configurations, and environmental specifications. Board Lock features in substitute parts provide mechanical retention enhancement without affecting electrical performance.

Frequently Asked Questions (FAQ)

Q: Can TFM-145-12-S-D-LC or TFM-145-22-S-D-LC be used as direct replacements for TFM-145-32-S-D?

A: Yes, provided the application accommodates the reduced Insulation Height. TFM-145-12-S-D-LC (0.290") and TFM-145-22-S-D-LC (0.360") both maintain identical electrical specifications, contact pitch, and row configuration. PCB layout and mating connector clearance must be verified for the specific height reduction.

Q: What is the functional difference between the main part and substitute parts?

A: The primary difference is Insulation Height and the addition of Board Lock features in substitute parts. Electrical performance, current rating, voltage rating, and operating temperature range remain identical across all three parts.

Q: Are all three parts suitable for the same environmental conditions?

A: Yes. All three parts operate across -55°C to 125°C, maintain UL94 V-0 flammability rating, and carry ROHS3 compliance. Moisture Sensitivity Level is 1 (Unlimited) for all variants.

Q: Does Board Lock affect connector compatibility?

A: Board Lock is a mechanical retention feature that does not affect electrical compatibility or mating with standard Tiger Eye™ TFM series receptacles. It provides additional mechanical stability during insertion and removal cycles.

Q: What inventory considerations apply to these substitutes?

A: TFM-145-32-S-D has 1043 units in stock, TFM-145-12-S-D-LC has 1089 units, and TFM-145-22-S-D-LC has 638 units available. Selection may be influenced by delivery requirements and stock availability.
